“…There are several explanations for the existence of home bias in portfolio investments. These include: (i) hedging motives in frictionless financial markets, that is, real exchange rate and nontradable income risk (Stockman and Dellas, 1989;Wheatley, 2001), (ii) higher asset trade costs in foreign markets (such as transaction costs, differences in tax treatments between national and foreign assets or differences in legal frameworks), (iii) informational frictions (Brenan and Cao, 1999;Portes and Rey, 2005;Leuz et al, 2010;Pedraza et al, 2020) and (iv) behavioral biases (Bailey et al, 2011;Riff and Yagil, 2016). While disentangling the contribution of each motive on the bias towards domestic assets is difficult, it is well-known that portfolio investments in foreign markets are influenced by market development in both the source and target countries, by investor familiarity with each market as suggested by common language, bilateral trade flows, and both geographic and cultural proximity (Chan et al, 2005).…”
